Real Housewives of New Jersey star Teresa Giudice’s motherAntonia Gorgadied on Friday, March 3 at 66 years old. The reality star took to Instagram to share a heartbreaking message to her fans about her mom’s death.

“Thank you for the love and support during this extremely difficult time,” the 44-year-old captioned a collage of photos with her mom. “My mother was a very cherished part of our family and she'll be deeply missed. Each and every one of your messages of love & support are so appreciated. Give her eternal rest O Lord and may your light shine on her forever.”

The matriarch of the Gorga/Giudice family passed away from natural causes, E! News reported. Antonia is survived by her husband Giacinto Gorga, their daughter Teresa and their 37-year-old son Joe Gorga. Joe’s wife, Melissa Gorga, also paid tribute to her mother-in-law with a touching Instagram tribute.

“May she Rest In Peace. She was a beautiful woman who loves her children & grandchildren so immensely,” the 37-year-old wrote in the caption of a family photo. “I watched Joe & Teresa sit by her side for the last three months, the heart in this family is strong [and] she will live in our hearts forever.”

Antonia was also known as Nonna to Teresa’s four daughters that she shares with her husband Joe Giudice, as well as Melissa and Joe’s two sons and daughter — who was named after her grandmother. Teresa’s oldest daughter Gia paid tribute to her Nonna on Instagram.

“Now I have another beautiful guardian angel watching over me. I love you,” the 16-year-old wrote.

The loss of her mother has left Teresa “inconsolable,” as the mother and daughter duo were very close, a source told Us Weekly. She has been in contact with her husband Joe — who is currently serving out a 41-month sentence for fraud at the Federal Correctional Institution in Fort Dix, NJ — and he is expected to be allowed to visit his family during this difficult time.
